Wild Fractions


These entertaining, imaginative resources from KET include standards-based interactives and videos for PreK-1 and for grades 5-8.

For the younger set, eight videos and interactives from Everyday Math for Preschoolers explore fun, age-appropriate examples of basic math concepts.

For grades 5-8, the collection offers 43 KET-produced resources from Math at the Core: Middle School, including 17 Scale City videos and interactives about proportional reasoning, 14 Wild Fractions animations and games that feature visual models for fraction multiplication and division, nine Logical Leaps interactives about number lines, and three Maritime Mysteries interactives involving Cartesian graphs.

Designed to appeal to diverse learners, KET resources provide real-world connections, opportunities to think more deeply about mathematics, and—for older students—ways to use both logic and computation to solve problems.

  • Modeling a Fraction Multiplication Word Problem

    This video illustrates a word problem involving the multiplication of fractions that requires students to find an unknown product based on a comparison of two quantities. One of the world’s largest insects, the Goliath beetle, is known for its strength as well as its size. The animation shows a beetle lifting many times its own weight and then models how to determine the number of pounds that the beetle is lifting. In the accompanying classroom activity, students watch the video, reproduce the visualization modeled in the video, and solve a problem using a visual model. This resource is part of the Math at the Core: Middle School Collection.
